Question
A ball (mass = 2 kg) in the figure is travelling horizontally at 15 m/s. It strikes the 8 kg block which is travelling down the plane at an angle shown in the figure. The coefficient of the restitution between the bodies is e = 0.65. Find out (a) speeds of the two bodies (ball and block) after the impact, (b) distance covered by the block in the upward direction of the plane before it stops momentarily and (c) average impulsive force between the ball and block, when the impact occurs for 0.0005 sec. The coefficient of friction between block and plane is µk = 0.4. 2 m/s 15 m/s 20°
